Drain connection
– machines with
drain pump (AP)
Observe the following instructions when connecting a drain with a
drain pump:
- The drain manifold (at least DN100; minimum diameter 4") can be
installed:
- under the floor
- to the ceiling
- Install and odor trap on site.
- Observe the maximum delivery head for the drain pump (see Tech-
nical data).
- If the machine is drained vertically towards to the ceiling, it is advis-
able to use pipelines instead of hoses. If necessary, DN25 to
DN40 (minimum diameter 1" to 1 9/16") pipes can be used. High
temperatures, pressures and mechanical loads from the pump
place excessive strain on the hose.
- Install the waste water line for connecting the drain hose next to the
machine.
- Hose feed-throughs in the side walls of the casing are not possible
for structural reasons.
- If you are installing several machines in a row, you can create a toe-
kick drip tray specifically for your requirements. You can place the
drain hoses in this tray.
Vent connection Ventilation to atmosphere must be fan assisted. Dry contacts are
available to alert the fan controls to start the fan. The permissible flow
rates can be found under Technical data at the end of this manual.
Provide an air intake of 8,829 ft³/h (250 m³/h) for each machine on the
unclean side to replace extracted air. Connect the machine to the
ventilation or air-conditioning system. If necessary, connect a steam
condenser upstream. Install the ducting with a slope in the direction
of the extract air flow. This prevents any condensate from flowing
back into the machine. Drain the system at the lowest point.
Install separate ducting for each machine. Ducting for several ma-
chines must not be combined!
Connection mod-
ule – fan control
9 dry contacts are available on the machine for the connection. The
connections are located on the unclean side in the top-box panelling.
The contacts can support a maximum load of
200–240V / 1A / 50–60Hz.
When assigning the dry contacts, it is not permitted to have a
standard voltage and, for example, an extra-low voltage next to
each other.
Maintain a sufficient distance between contacts with incompatible
voltages.
